MACHINE FOR MAKING PICTURE-MOLDINGS.

SPECIFICATION forming part of Letters Patent No. 34l,04=9, dated May 4,1886.

Application filed July 30, 1885. Serial No. 173,071. (1\'o model.)

To aZZ whom it may concern:

Be it known that I, SAMUEL A. PERRY, of the city and county of SanFrancisco, State of California, have invented an Improvement in Machinesfor Making Picture'Moldings; and I hereby declare the following to be afull, clear, and exact description of the same.

My invention relates to that class of machines for makingpicture-moldings in which a pat tern-roller and an underlyingfeed-roller are rotated in opposite directions, and the plastic materialis passed between them.

My invention consists in the novel construction by which thepattern-roller may be readily removed for the substitution of anotherwith a. different pattern, in the arrangement of power-transmittinggears between the two rollers, which permit the vertical adjustment ofthe pattern-roller, still preserving their engagement or mesh, and inthe general construction of the machine.

The object of my invention is to provide a simple and serviceablemachine of this class.

Referring to the accompanying drawings, Figure l is a perspective viewof my machine, showing the plastic material being fed through. Fig. 2 isa vertical cross-section through the feed-roller and its shaft. Fig. 3is a perspective view of the adjustable sleeves. Fig. 4 is an elevationshowing the arrangement'of gears.

A is a bench or frame, from which rise slotted standards B, in which theverticallyadjustable boxes 0 are mounted and are adapted to slide.

D is a roller, having formed upon its periphery any suitable pattern.

E is a roller or drum mounted in a transverse slot in the bench A, andlies directly below the pattern-roller D.

The pattern-roller is mounted in the boxes Gin the following manner,(shown particularly in Fig. 2:) cl is a shaft, which passes through thecenter of the roller and the vertically-adjustable boxes G, and isprovided with nuts at on its ends. Upon the shaft is journaled a sleeve,(1, to which the pattern-roller D is keyed or otherwise secured.Journaled in one of the boxes 0, and surrounding one end of the shaft(1, is a clutch'sleeve, d, the inner end or head of which is providedwith notches d The adjacent end of the sleeve d is provided with smalllugs or pins (1 which are adapted to fit in the notches of theclutch-sleeve. The object of this construction is to facilitate theremoval of the pattern-roller for the substitution of one of a differentpattern, and is thus accomplished: The nut on the end of the shaft beingloosened, said shaft is pulled out, and the sleeve d may then bedisengaged from the clutch-sleeve. Therollercanberemoved from its sleeveby taking out its key or other fastening. To put another in place, it iskeyed on the sleeve cl, which is then caused to engage the clutch-sleeve(P, and the shaft (2 is passed through both sleeves and its nutistightened up again. This enables me to use any character of patternroller without loss of time. The pattern-roller D is verticallyadjustable by means ofthe screws F, passing down through the standards Band connected with the boxes G. The upper ends of the screws areprovided with pinions g, which mesh with a central spurwheel, G, on ashaft, H, having a crank, it. By operating the crank-wheel the screws Fare moved up and down to vertically adjust the pattern-roller. On theend of the feedroller shaft is a crank, O.

The means for transmitting power from the feed-roller to thepattern-roller are as follows: On one end of the shaft of thefeed-roller E, Fig. 4, is a pinion, I, and on the end of theclutch-sleeve (1 which actuates the patternrollcr, is a pinion, J.Pivoted on the shaft of the feedroller is a curved double or slottedlink, K, in which is pivoted a pinion, L, and a pinion, M, the former ofwhich meshes with the pinion I and the latter with the pinion J. Saidpinions L and M mesh also with each other, thus forming a connectedchain of gearing. From the upper end of the link K extends a pivotedretaininglink, N, to the shaft of the pattern-roller. XV hen thepattern-roller D is raised, the pivotedlink K is drawn in to keep itspinions M and L to their engagements, and when said roller is loweredthe reverse movement of link K takes place, where by the engagement ofthe gears is maintained.

The operation of my machine is as follows: The plastic material isplaced upona strip of suitable length, and is fed through between theroller E and the roller D, whereby the material is molded by the latterroller. By reason of the adjustment of the pattern-roller moldings ofdifferent thicknesses may be passed through, the limits of adjustment ofsaid roller being sufficient for any case, and the machine continues tobe operative, no matter how great the adj ustment,because of the systemof gears, which maintain their mesh, as described.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is

1. In a machine for making picture-moldings, the pattern-roller D, incombination with the removable supporting-shaft d, the sleeved,journaled on the shaft and carrying the pattern-roller, and therotating clutch-sleeve d journaled on the shaft and engaging the sleeved, substantially as herein described.

2. In a machine for making picture-moldings, the pattern-roller D, incombination with the removable supporting-shaft d, the sleeve (2,journaled on said shaft and carrying the pattern-roller, said sleevehaving lugs d on its end, and the clutch-sleeve (1 to which power isapplied, and having the notches d in its inner end, with which lugs ofsleeve (1 engage, substantially as herein described.

3. In a machine for making picture-moldings, the slotted standards B ofa frame, the vertically adjustable or sliding boxes(] in said standards,and the removable shaft 01 in the boxes, in combination with thepattern-roller D, the sleeve (1, carrying the roller and journaled onthe shaft, and the rotating clutchsleeve d journaled in one of the boxesand on the shaft, and engaging the sleeved, substantially as hereindescribed.

4. In a machine for making picture-moldings, the feed-roller E, to whichpower is applied, and the vertically-adjustable patternroller D, mountedabove, in combination with the power-transmitting devices between saidrollers, consisting of the pinion I on the feedroller shaft, the pinionJ, actuating the pattern-roller, and the adjustable intermediatepinions, L and M, substantially as herein described.

5. In a machine for making picture-moldings, the feed-roller E, to whichpower is applied, and the vertically-adjustable patternroller D above,in combination with the means by which the power of the feed-roller E istransmitted to the pattern-roller, consisting of the pinion I on thefeed-roller shaft, the pinion J,by which the pattern-roller is driven,the intermediate pinions, L and M, the link K, pivoted on thefeed-roller shaft and carrying the intermediate pinions, and the pivotedretaining-link N from link K to the shaft of the pattern-roller,substantially as herein described.

6. Arnachine for makingpicture-moldings, comprising the bench A, havingstandards B, the feed-roller E, mounted transversely in a slot in thebench, the removable pattern-roller D, and vertically-adjustable boxes 0in the standards, and carrying the aXis or shaft of the pattern-roller,the crank O and pinion I on the feed-roller shaft, the pinion J,actuating the pattern-roller, and the adjustable intermediate pinions, LM, all arranged and adapted to operate substantially as hereindescribed.

In witness whereof I have hereunto set my hand.
